CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 14/932,785, filed Nov. 4, 2015, which claims priority to U.S. Provisional Patent Application No. 62/175,053, filed on Jun. 12, 2015, the contents of each of which are incorporated by reference herein in their entirety and for all purposes.

BACKGROUND

Field of the Invention

The field relates to a bracket for securing studs in single- or multi-story buildings.

Description of the Related Art

Constructing single- or multi-story buildings can be an expensive and time-consuming activity. For example, in some buildings, a frame for a wall may include multiple studs that are nailed or otherwise secured to a sill which can be disposed along the floor or ceiling as part of a larger wall structure. The builder often uses holddowns to secure the studs to the building foundation, and/or to other holddowns on adjacent floors. Some holddowns can be expensive and complicated to assemble, and not suitable for two- to five-story buildings. For example, the builder may use multiple bolts and fasteners to assemble the holddown and secure the studs to the foundation. An example of a holddown connected between closely spaced studs is described in U.S. Pat. No. 6,389,767, which is incorporated by reference herein. Accordingly, there remains a continuing need for improved devices and methods for installing a frame of multiple studs in a building.

SUMMARY

In one embodiment, a bracket for a holddown is disclosed. The bracket can include a base section sized and shaped to extend over end surfaces of a pair of spaced apart studs, the base section including an aperture to receive a rod therethrough. First and second arms can extend from the base section. the first and second arms can be spaced apart to extend over outer side surfaces of the pair of spaced studs, the first and second arms having a plurality of fastener openings.

In another embodiment, a frame for a building is disclosed. The frame can comprise a bracket comprising a base section and first and second arms extending transversely from the base section. The first and second arms can be spaced apart from one another, the base section comprising an aperture. A pair of studs can be spaced from one another and disposed between the first and second arms. An outer side surface of a first stud of the pair of studs can be connected to the first arm and an outer side surface of a second stud of the pair of studs can be connected to the second arm.

In yet another embodiment, a method of manufacturing a building is disclosed. The method can comprise inserting first and second studs between first and second arms of a bracket, the first and second arms extending from a base section of the bracket. The method can include spacing the first and second studs from one another such that there is a stud spacing between respective inner side surfaces of the first and second studs. The method can include securing an outer side surface of the first stud to the first arm. The method can include securing an outer side surface of the second stud to the second arm.

DETAILED DESCRIPTION

Various embodiments of a bracket for multi-story buildings are disclosed herein. The embodiments disclosed herein can utilize a single U-shaped bracket with simple fasteners to secure multiple studs (e.g., a pair of studs, or more than two studs) in a frame of a building. The arrangements disclosed herein can advantageously enable the efficient and cost-effective assembly of single- or multi-story buildings that can withstand high loading conditions (e.g., accumulated vertical loads of up to 50,000 lbs). Embodiments are applicable to wood or metal framing elements for building construction.

For example, in some embodiments, a U-shaped bracket can be used to secure two adjacent but spaced studs to a building foundation, e.g., by way of a wall frame element which is disposed along or on the foundation of the building. The U-shaped bracket can include a base section, and two arms extending transversely from the base section and spaced apart from one another sufficiently to accommodate therebetween two studs, where the inner surfaces of the studs are spaced apart from one another. The studs may have a larger, major side surface and a smaller, minor side surface. For example, standard 2″×4″ studs may have a major side surface having a width of about 3.5″ and a minor side surface having a width of about 1.5″. In some embodiments, a pair of studs may be positioned between the two arms such that the arms abut the major side surfaces of each stud, while the base section extends over the end surfaces of the studs (with or without an intervening plate washer). As illustrated herein, each arm of the bracket can be positioned on an outer major side surface of the respective stud, e.g., the large side surfaces of the studs that face away from one another. In other embodiments, the arms may abut the smaller, minor side surfaces of the studs. The studs can be fastened to the bracket by way of screws, nails, etc. The use of simple fasteners such as wood screws may provide various cost advantages as compared with more complicated fasteners, such as nut-and-bolt arrangements. The bracket may be connected to a horizontal building member with a connector, such as a screw, a nail, a bolt, or a welded joint. The horizontal building member can form part of a floor or ceiling, or can form part of a wall structure (e.g., a sill) disposed adjacent a ceiling or a floor. In some arrangements, the studs and the horizontal building member may comprise wood. In other embodiments, the studs and/or the horizontal building member may comprise a metal, such as steel, aluminum, etc.

The arms can be spaced apart by a suitable predetermined distance. For example, many buildings are built having studs spaced apart by a standard distance, which can define, in combination with the widths of the two studs, the separation between the arms of the bracket. For example, the arms of the bracket may be spaced apart by a separation distance of at least 4 inches, for example, by a separation distance of at least 6 inches. The separation distance between the arms can be in a range of 4 inches to 27 inches, or more particularly, in a range of 6 inches to 27 inches, for example, in a range of 6 inches to 12 inches. In some arrangements, the arms can be spaced by a separation distance of 5 inches to 8 inches, e.g., in a range of 5 inches to 7 inches. Other separation distances may be suitable.

The bracket may comprise a metal, such as steel. In various arrangements, the bracket can comprise 12 gauge steel, 13 gauge steel, 14 gauge steel, 15 gauge steel, 16 gauge steel, 17 gauge steel, 18 gauge steel, 19 gauge steel, 20 gauge steel, etc., or ranges between any two of the above steel weights or thicknesses. In various embodiments, the thickness of the bracket can be at least ⅛ inch thick, for example, at least ¼ inch thick. For example the thickness of the bracket can be in a range of ⅛″ to 1″, or in a range of ¼″ to 1″. For other materials, such as aluminum, fiberglass, plastic, carbon-fiber composites, etc., the skilled artisan can readily determine equivalent weights or thicknesses to resist equivalent loads. The studs can comprise wood, e.g., pine, oak, etc. In some embodiments, the studs can comprise a metal, such as steel, aluminum, etc.

As explained herein, the studs may rest on a plate washer disposed between the two arms of the bracket. In other arrangements, the plate washer can be positioned on the base section of the bracket between the studs. The plate washer can assist in bearing the load from the building. In still other embodiments, no plate washer may be used at all. The plate washer and the base section of the bracket may comprise an opening sized and shaped to receive an elongate tie member. The elongate tie member can comprise a cable or a rod, which can be a threaded rod, particularly an all-thread rod. The tie member (e.g., rod or cable) can be inserted through the opening to secure the bracket and studs to the foundation of the building. A nut can be used to tighten the rod.

Advantageously, the embodiments disclosed herein can be used in single- or multi-story buildings. For example, in some arrangements, as explained herein, the tie member (e.g., a rod) can pass from floor-to-floor to enhance the stability of the building. In such arrangements, the tie member can pass through a first bracket located on one story of the building (e.g., on the floor or ceiling of a particular story) and also through a second bracket located on another story of the building (e.g., on the adjacent ceiling or floor of the other story). For the bottom floor of a building, the tie member may extend into the foundation (e.g., concrete).

To assemble a portion of the building, the builder may provide a pre-assembled frame member including a plurality of studs that have been fastened to the bracket. In other embodiments, the studs may be fastened to the bracket at the building site. The builder may nail (or otherwise fasten) the base section of the bracket to the plate washer and the studs. In some arrangements, the plate washer may not be directly fastened to the bracket, but may lie between the arms of the bracket so that the studs can bear against the plate washer. In still other arrangements, a plate washer may not be used. In other embodiments, the base section of the bracket may be thickened, roughened, and/or corrugated so that the base section of the bracket may act as the plate washer to support the studs. The studs, bracket, and plate washer may be lifted perpendicular to a horizontal building member, such as a sill which may be configured to be disposed along a floor or a ceiling of the building. The studs, bracket, and plate washer may be connected to the sill off-site and transported to the building for installation. In other arrangements, the studs, bracket, and plate washer may be connected to the horizontal building member during installation in the building. A rod may be inserted through openings in the base section of the bracket and the plate washer. A connector, such as a nut, can be threaded onto the rod to tighten the assembly.

Thus, the embodiments disclosed herein can advantageously enable the manufacture of single- or multi-story buildings at reduced costs and improved efficiency as compared with other techniques. For example, it can be relatively inexpensive to use simple fasteners to connect a pair of studs to a single U-shaped bracket, as compared with other techniques which utilize more expensive fasteners and more complicated assembly methods. Furthermore, in some embodiments, the frame members can be assembled offsite, e.g., the studs can be connected to the U-shaped bracket and plate washer and carried to the building site for efficient assembly.

FIG. 1 is a schematic side cross-sectional view of a multi-story building 1, in accordance with one embodiment. The building 1 of FIG. 1 has three stories, but it should be appreciated that any suitable number of stories may be built. Each story of the building 1 can be built by assembling one or more frames 100 (which at least partially define the walls of the building 1) and connecting the frames 100 together by way of corresponding holddown assemblies 10. For example, one or more frames 100A for the first story of the building 1 can be secured to a foundation 90 of the building 1. The one or more frames 100B for the second story of the building 1 can be connected to the frame(s) 100A for the first story by way of one or more holddown assembly (assemblies) 10, and one or more frames 100C for the third story can be connected to the frame(s) 100B for the second story by way of one or more additional holddown assembly (assemblies) 10. In some embodiments, the frames 100 can be pre-assembled off-site and can be incorporated into the building 1 at the building site. Pre-assembling the frames 100 off-site can enable workers to efficiently construct the building and lower labor costs. In other embodiments, the frames 100 can be built on site as the building is being constructed. It should be appreciated that, although various embodiments are disclosed in the context of a multi-story building, and are particularly advantageous for the construction of 3-4 story buildings, the bracket 3 and associated components may also be used with a single story building.

Each frame 100 of the building 1 can include a pair 2 of studs 2 a, 2 b and a bracket 3 to which the studs 2 a, 2 b are secured. In some embodiments, the frame 100 can also include one or more horizontal building members, such as a lower sill 5 (for example, to be disposed along a floor of the building) and/or an upper sill 9 (for example, to be disposed along a ceiling of the building). The horizontal building members can form part of a wall, floor or ceiling. In embodiments as shown, where the horizontal building members are sill plates, the sills and the studs can form or define part of a wall structure of the building when installed. In such embodiments, the studs 2 a, 2 b can be connected to the bracket 3 by way of a suitable fastener (such as a screw, nail, bolt, weld joint, etc.). The bracket 3 can be connected to a corresponding lower sill 5 and/or upper sill 9 by way of a suitable fastener (such as a screw or nail). The studs 2 a, 2 b, the lower sill 5, and the upper sill 9 can comprise wood posts in various embodiments, such as 2×4 boards, 4×4 boards, etc. Any suitable type of wood can be used for the studs 2 a, 2 b, the lower sill 5, and the upper sill 9, such as pine, oak, etc. In other arrangements, the studs 2 a, 2 b, lower sill 5, and upper sill 9 can comprise a metal, such as steel, aluminum, etc.

The studs 2 a, 2 b and bracket 3 from one story (e.g., the first story) can be secured to corresponding studs 2 a, 2 b and bracket 3 from another story (e.g., the second or third story) by way of a tie member, such as the illustrated a rod 4, and a connector 6. Although the tie member of FIG. 1 is illustrated as the rod 4, in other embodiments, the tie member can comprise a cable or other suitable member. For example, a short rod 4 a can connect two frames 100 that are disposed on adjacent stories, such as the first and second stories of the building 1. As shown in FIG. 1, a first end portion 91 of the short rod 4 a can connect to the bracket 3 on the second story, while a second end portion 92 of the short rod 4 a can connect to the bracket 3 on the first story. A plate washer 7 can be disposed within each bracket 3 and can help support the vertical loading from the building 1. Connectors 6 (such as a nut) can be threaded and tightened on the first and second end portions 91, 92 of the short rod 4 a to secure the frame 100B on the second story to the frame 100A on the first story.

Further, in some embodiments, a long rod 4 b can be used to connect frames that are disposed on non-adjacent stories of the building 1. For example, as shown in FIG. 1, a first end portion 93 of the long rod 4 b can be coupled with a bracket 3 on the third story of the building 1. A second end portion 94 of the long rod 4 b can be coupled with a bracket 3 on the first story of the building 1. Respective connectors 6 (such as a nut) can be threaded and tightened to secure the frame 100C of the third story to the frame 100A of the first story. A ground rod 4 c and connector 6 can connect the one or more frames 100A of the first story to the foundation 90. The bracket 3, fasteners, and plate washer 7 coupled with the lower sill 5 on the first story of the building 1 can adequately support the vertical building loads of the illustrated three-story building. For example, in some arrangements, each story of the building 1 can contribute about 5,000 pounds of loading, such that the brackets 3 and plate washers 7 disposed on the first story of the building 1 support about 15,000 pounds of vertical loading for the three-story building schematically illustrated in FIG. 1. In various embodiments, the bracket 3 can support loads in a range of 1 lb to 40,000 lbs, e.g., up to about 25,000 lbs.

FIGS. 2A-2D are schematic perspective views of the bracket 3, according to various embodiments. The bracket 3 can be generally U-shaped and can include a base section 20 and a pair 24 of arms 24 a, 24 b extending transversely from the base section 20. An aperture 21 can be formed through the base section 20. The aperture 21 can be sized and shaped to receive the rod 4 (e.g., any of rods 4 a-4 c) described above in connection with FIG. 1. The base section 20 may also include a plurality of openings 33 for receiving fasteners (such as screws or nails) which can be used to secure the bracket 3 to one or more of a lower sill 5, an upper sill 9, and/or a plate washer 7. Further, each arm 24 a, 24 b can include a plurality of fastener openings 22 through which fasteners (e.g., screws or nails) can be received to secure the arms 24 a, 24 b to respective studs 2 a, 2 b.

The bracket 3 can have a length l which defines a separation distance between the two spaced arms 24 a, 24 b. The length l can be selected to provide for a predetermined spacing between the pair 2 of studs 2 a, 2 b. For example, the length l can be defined between inner surfaces of the arms 24 a, 24 b. In some embodiments, the length l or separation distance can be at least 4 inches, for example, the length l or separation distance can be at least 6 inches. The separation distance between the arms can be in a range of 4 inches to 27 inches, e.g., in a range of 6 inches to 27 inches, for example, in a range of 6 inches to 12 inches. In some arrangements, the separation distance can be in a range of 5 inches to 11 inches, in a range of 5 inches to 9 inches, or in a range of 6 inches to 9 inches. In some arrangements, the arms can be spaced by a separation distance of in a range of 5 inches to 8 inches, or more particularly in a range of 5 inches to 7 inches. The bracket 3 can also have a width w which can be defined as the width of each arm 24 a, 24 b. The width w of the bracket 3 can be sized to fit against the major surfaces of the studs 4 a, 4 b. The width w can be in a range of 2 inches to 8 inches, or in a range of 2 inches to 6 inches. In some embodiments, the width w of the bracket 3 can be in a range of 3 inches to 8 inches, or more particularly, in a range of 4 inches to 6 inches. In some embodiments, the width w can be in a range of 2.5 inches to 3.5 inches, e.g., about 3 inches. In other embodiments, the width w can be in a range of 4.5 inches to 5.5 inches, e.g., about 5 inches. The width w can match the width of the studs 2 a, 2 b to be accommodated within the bracket 3.

The height h of the bracket 3 can be any suitable height. For example, as shown in FIGS. 2A-2D, the bracket 3 may have a relatively small height h₁ (FIGS. 2A and 2D), an intermediate height h₂ (FIG. 2B), or a relatively large height h₃ (FIG. 2C). A bracket 3 with a relatively small height h₁ may support fewer fasteners along the arms 24 than a bracket 3 with an intermediate height h₂ or a relatively large height h₃, which in turn may support a smaller load than brackets with the intermediate or larger heights.

The bracket 3 may comprise a metal, such as steel, aluminum, etc. In various arrangements, the bracket can comprise 12 gauge steel, 13 gauge steel, 14 gauge steel, 15 gauge steel, 16 gauge steel, 17 gauge steel, 18 gauge steel, 19 gauge steel, 20 gauge steel, etc., or ranges between any two of the above steel weights or thicknesses. In various embodiments, the thickness of the bracket 3 can be at least ⅛ inch thick, for example, at least ¼ inch thick. For example the thickness of the bracket 3 can be in a range of ⅛″ to 1″, or in a range of ¼″ to 1″. For other materials, the skilled artisan can readily determine equivalent weights or thicknesses to resist equivalent loads. In other embodiments, the bracket 3 can comprise other structural materials, such as fiberglass, plastic, or a carbon fiber composite material.

Furthermore, the bracket 3 of FIG. 2D illustrates another arrangement in which the bracket 3 can be connected to the studs 2 a, 2 b and the corresponding horizontal building member (e.g., sill plate). For example, the bracket 3 can include one or more flanges 130 (e.g., a pair of flanges) extending inwardly from each arm 24 a, 24 b of the bracket 3. Thus, as shown in FIG. 2D, each flange 130 can extend from outer ends of the corresponding arm 24 a or 24 b inwardly towards the opposing arm. The flanges 130 can include one or more flange openings 131 through which corresponding flange fasteners (such as screws, nails, etc.) may be inserted to secure the flanges 130 to the studs 2 a, 2 b. The flanges 130 can comprise a planar piece of metal coupled to or formed with the arms 24 a, 24 b. Although a pair of opposing flanges 130 is shown to be extending from each arm 24 a, 24 b, it should be appreciated that, in some embodiments, only one flange 130 may extend from a particular arm 24 a.

Moreover, the bracket 3 of FIG. 2D can include one or more tabs 140 extending downwardly from the base section 20 of the bracket 3. The tabs 140 can be coupled to or formed with the base section 20 and can extend transversely relative to the base section 20. In some embodiments, the tabs 140 can comprise a planar piece of metal. The tabs 140 may extend the full width of the base section 20 in some arrangements. In other arrangements, the tabs 140 may extend only partially along the width of the base section 20. In some embodiments, for example, multiple tabs 140 may be disposed and spaced apart from one another along one side of the base section 20. Although a pair of tabs 140 is illustrated in FIG. 5D, it should be appreciated that, in other embodiments, only a single tab 140 may extend downwardly from the base section 20. The tabs 140 can include one or more tab apertures 141 sized and shaped to receive corresponding tab fasteners (such as screws, nails, etc.). The tab fasteners can be used to secure the tabs 140 (and thereby the bracket 3) to a horizontal building member or sill.

Furthermore, although the tabs 140 are shown in FIG. 2D as extending downwardly from the base section 20, in other embodiments, the tabs 140 can extend from other portions of the bracket 3 which may be suitable for fastening the bracket 3 to a horizontal building member (e.g., sill). For example, in some embodiments, horizontally-extending tab(s) may extend outwardly from the outer surfaces of one or both of the arms 24 a, 24 b, e.g., at or near where the arms 24 a, 24 b join or extend from the base section 2. Such outwardly-extending tabs may extend away from the bracket by a suitable distance and may comprise one or more apertures through which fasteners can be inserted to secure the outwardly-extending tabs (and thereby the bracket) to a top surface of the horizontal building member.

FIG. 3A is a side view of a portion of an arm 24 a of a bracket 3, according to one embodiment. In particular, the bracket 3 of FIG. 3A can have a width of about 3 inches and can have a plurality of rows r₁ . . . r_(n) of fastener openings 22. The fastener openings 22 can be sized and shaped to receive fasteners (such as screws or nails) to secure a stud (e.g., stud 2 a) to the arm 24 a. As shown in FIG. 3A, the fastener openings 22 of a first row r₁ can be staggered along the width of the arm 24 a relative to the fastener openings 22 of a second row r₂. For example, the horizontal spacing between a fastener opening 22 on the first row r₁ and an adjacent staggered fastener opening 22 on the second row r₂ can be in a range of 0.5 inches to 1.5 inches, e.g., about 1 inch. In other embodiments, the horizontal spacing between a fastener opening 22 on the first row r₁ and an adjacent staggered fastener opening 22 on the second row r₂ can be in a range of 0.15 inches to 0.75 inches, e.g., in a range of 0.2 inches to 0.6 inches. Further, the horizontal spacing between adjacent fastener openings 22 on a particular row r_(n) can be in a range of 0.5 inches to 2.5 inches, e.g., about 2 inches. In some embodiments, the horizontal spacing between adjacent fastener openings 22 on a particular row r_(n) can be in a range of 0.2 inches to 0.6 inches. The row spacing vertically between adjacent rows r_(n-1) and r_(n) along the height of the bracket 3 can be in a range of 0.2 inches to 1.5 inches, e.g., about 0.5 inches in some embodiments. The center-to-center spacing of the openings 22 may be related to the load capacity which the fasteners can carry. For example, in some arrangements, it may be desirable to space the openings from one another by at least a minimum fastener spacing so that the fasteners can act at their full load capacity.

FIG. 3B is a side view of a portion of an arm 24 a of a bracket 3, according to another embodiment. In particular, the bracket 3 of FIG. 3B can have a width of about 5 inches and can have a plurality of rows r₁ . . . r_(n) of fastener openings 22. The fastener openings 22 can be sized and shaped to receive fasteners (such as screws or nails) to secure the stud 2 a to the arm 24 a. As shown in FIG. 3B, the fastener openings 22 of a first row r₁ can be staggered along the width of the arm 24 a relative to the fastener openings 22 of a second row r₂. For example, the horizontal spacing between a fastener opening 22 on the first row r₁ and an adjacent staggered fastener opening 22 on the second row r₂ can be in a range of 0.5 inches to 1.5 inches, e.g., about 1 inch. Further, the horizontal spacing between adjacent fastener openings 22 on a particular row r_(n) can be in a range of 0.5 inches to 2.5 inches, e.g., about 2 inches. The row spacing vertically between adjacent rows r_(n-1) and r_(n) along the height of the bracket 3 can be in a range of 0.2 inches to 1.5 inches, e.g., about 0.5 inches in some embodiments.

FIG. 4A-4C are schematic perspective views showing the brackets 3 of FIGS. 3A-3C connected to respective pairs 2 of studs 2 a, 2 b. As shown in FIGS. 4A-4C, each stud 2 a, 2 b can include opposing major side surfaces 27 and opposing minor side surfaces 28. The major side surfaces 27 are larger than the minor side surfaces 28. For example, the side surfaces 27, 28 of each stud 2 a, 2 b can define dimensions n×m, with m>n. As one example, a 2×4 stud may have dimensions of about 1.5 inches by 3.5 inches, where n=1.5 inches and m=3.5 inches. In other embodiments, n may equal m, such as in the case of 4×4 posts or studs such that all side surfaces can have approximately the same surface area and width. In FIGS. 4A-4C, the arms 24 a, 24 b abut and mechanically connect to major side surfaces 27 of the studs 2 a, 2 b. For example, the arms 24 a, 24 b can abut and connect to outer side surfaces 27 of the pair 2 of studs 2 a, 2 b, which outer surfaces face away from one another. In other embodiments, however, the arms can be configured to abut and connect to the minor side surfaces of the studs, where the studs are oriented at 90° relative to the illustrated orientations.

The arms 24 a, 24 b can be spaced so as to provide a desirable stud spacing p between each pair 2 of studs 2 a, 2 b, e.g., between opposing inner surfaces 27 of the studs 2 a, 2 b. For example, the stud spacing p can be in a range of 1 inch to 8 inches, in a range of 2 inches to 4 inches, e.g., about 3 inches in some embodiments. In some arrangements, the stud spacing p can be in a range of 4 inches to 7 inches. The spacing p of the studs 2 a, 2 b can be sufficiently large to accommodate the rod 4 (FIG. 1) or other tie member therebetween for securing the studs 2 a, 2 b and bracket 3 to the building 1, with sufficient leeway to allow hand or tool tightening of a nut on the rod 4. In the embodiments of FIGS. 4A-4C, end surfaces 25 of the studs 2 a, 2 b abut the base section 20 of the bracket 3. However, it should be appreciated that a plate washer 7 (FIGS. 5A-5C) may intervene between the base section 20 and the end surfaces 25 of the studs 2 a, 2 b, as explained in detail herein.

FIG. 5A is a schematic side view of the plate washer 7, according to one embodiment. FIG. 5B is a top plan view of the plate washer 7 of FIG. 5A. The plate washer 7 can be sized and shaped to be positioned between the arms 24 a, 24 b of the bracket 3. In some embodiments, the end surfaces 25 of the studs 2 a, 2 b can bear against the plate washer 7, as shown in FIG. 5C. The plate washer 7 can thereby bear the load of the building 1 as transmitted by the studs 2 a, 2 b. In such embodiments, the plate washer 7 can be suitably sized so as to extend underneath the spaced apart studs 2 a, 2 b between the arms 24 a, 24 b of the bracket 3.
